` Application file d June 26, 1900. .Serial No. 21,699. (No model.)

To @ZZ whom, t 71mm/ concern:

Be it known that I, SIMEON O. LAwLoR, a citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Machines for Washing Windows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in windowcleaners, and particularly to that class of such devices by means ot' which the outer surfaces of the window may be cleaned by a person operating inside of the house, whereby the exposure and danger of falling from the window-sill are avoided, the object of the invention being to provide an improved .zo device of this class by which the desired operations may be performed in the least possible time and with the least possible expenditure of labor.

With this object in view the invention consists in an improved window-cleaner of the class mentioned, the construction, arrangement, and combination of the parts of which will be hereinafter fully described and afterward specically set forth in the claims.

3o In the accompanying drawings, Figure 1 is a view in side elevation of a window-cleaner constructed in accordance with myinvention, the horizontal hollow supporting rod or tube and a portion of the window-pane being shown in vertical section. Fig. 2 is a vertical sectional view taken on the plane indicated by the dotted line 2 2 of Fig. 1. Fig. 3 is a detail view, in side elevation,\of the frame or coupling for connecting the vertical standard ,4o with the horizontal supporting rod or tube,

a portion of the horizontal rod being shown threaded into the frame. Fig. 4 is a similar View, the horizontal rod or tube being secured in the frame by a spring or catch. Fig. 5 is a detail sectional view on the broken line 5 5 of Fig. 1, the vertical tubular standard being shown as provided with a longitudinal groove in one side. Fig. 5n is a similar view, the vertical tubular standard being provided with a 5o rib instead of a groove. Fig. 5b is a similar view, the vertical hollow standard being fiattened on one side instead of being ribbed or grooved. Fig. 6 is a top plan view of the inner or handle end of the horizontal supporting-bar. Fig. 7 is a detail View in elevation 55 of the window-cleaning brush. Fig. 8 is a sectional view on the broken line 8 l8 of Fig. 1 looking downwardly, as indicated by the arrows.

Like numerals mark the saine parts wher- 6o ever they occur in more than one figure of the drawings.

Referring to the drawings by numerals, 10 indicates a hollow vertical standard or tubular column upon which is mounted to slide vertically a sleeve 11, provided with antifriction and guide rollers 12, mounted on bolts 13, which also serve to hold the two sides of the sleeve 11 in position to fit upon the standard 10. These rollers 12- may be formed on 7o their peripheries to fit into or against either a longitudinal groove 14 or a longitudinal rib 15 or a flat side 16 of the vertical standard, as shown, respectively, in Figs. 5, 5a, and 5b. Projecting laterally from that side of sleeve. 11 opposite to the rollers 12 is a horizontal tube 17, in which is secured a smaller tube 18 by means of a set-screw 19, as in Fig. 1,01'

a spring-catch 20, as in Fig. 8. Projecting from the smaller tube 18 are spring-wires 21, 8o which carry at their outer ends a suitable window-cleaning brush 22, in this instance shown in the well-known form of the rubber window-cleaner.

23 indicates a sleeve or coupling secured by 85 means of clamp-screws 24 upon the lower portion of the vertical frame 10, in which is secured a horizontal supporting rod or tube 25 by means of a set-screw 26, as shown in Fig.

1, or by threading it into the sleeveor coup- 9o ling, as at 27 in Fig. 3, or by means of a springcatch 28, as in Fig. 4. Adjustably mounted to slide upon the horizontal supporting rod or tube 25 is a collar 29, upon which is formed or mounted a carriage 30, carrying rollers 31 95 and 32 and extended upwardly, as at 33, the extension being formed with a nick 34, as shown in Fig. 2. The carriage 30 is mounted to slide laterally of the window-pane and horizontal tube 35, held in position between the roo.

sides of the Window-frame in the manner hereinafter described, the grooved rollers 31 bearing upon the lower face of said tube and the roller 32 upon the upper face thereof. Within the tube 35 is acentral plug 36,against each end of which is placed a spiral spring, as at 37 and 3S, normally pressing outward against the enlarged heads or inner ends 39 and 40 of screws 4l and 42, which are provided on their outer ends with suitable pads or heads 43 and 44 to bear against the inner faces of the sides ot' the window-frame. Upon these screws are milled or plain nuts 45 46, which when the screws 4l and 42 are pressed outward by the springs 37 and 38 into contact with the window-frame are turned up tight against the ends of the tube 25 or of a lengthening-sleeve 47, said nuts being turned by any suitable means, -preferably by small bars or marline spikes 48 49, tting into radially-arranged holes provided in the periphery of the nuts.

In dotted lines at 50 in Fig. lis shown a weight suspended by a cord 5l, which passes up over a pulley 52, journaled in the upper end of the standard 10, and downward again, its end being secured in any suitable manner to the top of the tube 17. Tothe bottom of the tube 17 is secured a cord 53, which passes downward under a pulley 54, mounted in the frame or coupling 23, and thence inward to the carriage 30, Where its outer end may be secured in the nick 34 or any other suitable clamp when desired. The horizontal tube or rod 25 may be provided with any suitable shape of handle, as shown at in Figs. land 6, and the sleeve 29 may he secured in any position on said rod or tube 25 by means of a spring-catch 56, as shown in Figs. 1 and 2, or by means of a set-screw, if desired,

In the operation of my invention the tube 36 is placed in position between the sides of the window-frame,with the other parts mounted thereon, and secured in such position by means of the springs 37 and 38 and nuts 45 and 46, as before described. In this position the collar 29 and its carriage, together with the horizontal tube or bar 25, the vertical standard lO, and all other parts of the device, are free to be moved laterally on the tube 36, and this lateral movement of the standard l0 carries with it the brush-cleaner 22, held normally in contact with the window-pane 57 by means of the spring-wires 21. This provides for bringing the brush into contact with all parts of the width of the window-pane, and while in any of these positions, the vertical standard lO being outside the window-frame and the handle 55 inside, the brush 22 may be reciprocated vertically in contact with the window-pane by drawing outward on the cord 53 to draw said brush downward, and by the Weight 50, through the cord 5l, drawing the brush upward. By means of this double or lateral and vertical movement all parts of the outside of the window-pane may be reached by the brush.

The provision of the top and bottom friction-rollers on the sleeve 11 to run in contact with either the groove or rib or flat side of the vertical standard assures the more easy reciprocation of the sleeve ll on the standard 10 and prevents the frame from sticking or cramping, to which it is liable when provided with a single roller. The provision of the sleeve or coupling 23 renders the vertical standard l0 adjustable with relation to the horizontal tube or bar 25 and the tube or bar 25 removable at will. The provision of the carriage 30, with its triple rollers, renders the movement of the operative parts laterally on the fixed tube 36 much more easy and free from interruption by sticking or cramping. The provision of the adjusting collar or sleeve 17 amounts to an extension of the supporting-tube 36, thus permitting the carriage 30 to be moved much nearer to the sides of a wide window-frame than would be possible without them.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
